Cable Matters USB C to 10Gb Ethernet Adapter, Low-heat and Silent
- Real-World Speed: ~7Gbps on Windows / ~5Gbps on macOS, 10Gb Ethernet to USB C, Compatible with USB4 and Thunderbolt 5/4/3
- 10GbE Performance & USB-C Requirements: Upgrade to fast wired networking with this USB C to 10Gb Ethernet adapter, supporting 10G/5G/2.5G/1G/100M auto-negotiation for broad compatibility. Great for NAS access, large backups, content workflows, and low-latency gaming. Note: 10GbE is the theoretical link rate; real-world Windows throughput is typically ~7Gbps depending on setup. For best results, use a USB 3.2 Gen 2x2 (20Gbps) USB-C port or higher.
- Real-World macOS Speed: Compatible with Thunderbolt 3/4/5 and USB4 ports. On Macs, macOS may report a 5Gb link rate, while typical real-world throughput is ~5Gbps depending on the Mac model, network equipment, cabling, and test method. We continuously validate macOS performance and publish the latest notes and updates on our support page.
- Stable Performance with Advanced Chipset: Powered by the Realtek RTL8159 USB 10G c

1Ideal for NAS Networking2Perfect for Work1Solid Construction2Compact Size Is this adapter compatible with Thunderbolt 4 or USB4 ports?
Yes, the adapter is fully compatible with Thunderbolt 3, Thunderbolt 4, USB4, and standard USB-C ports that support data transfer.
Im not getting the expected network speed with this adapter. What should I do?
Install the latest Realtek PCIe FE/GbE/2.5GbE/5G/10G driver. Although the adapter is plug-and-play, the default system driver may limit performance. Updating the driver may improve speed and stability.
What settings on my router or switch can affect 10Gbps performance?
Check the Flow Control setting on your router or network switch. If it is enabled, try disabling it and test the connection again, as Flow Control may reduce 10Gbps throughput on some networks.
Is this adapter backward compatible with 1Gb or 100Mbps networks?
Yes, the adapter is backward compatible and will function at 1Gbps or 100Mbps speeds when connected to slower networks or routers.
What real-world speed should I expect on Windows and macOS?
Real-world throughput varies by host and network. Typical results are ~7Gbps on Windows and ~5Gbps on macOS when using a 20Gbps+ USB-C port, 10GbE equipment, and Cat6/Cat6a cabling. On macOS, use Autoselect instead of 5000Base-T for higher speed.
